ap0) and Charge Symmetry Breaking-HW problems [postscript] by Gerald Miller and Antonio C. Fonseca
Schedule of the CSB-II Meeting (April 19, 2002)
Charge-symmetry breaking (CSB) is a consequence of the quark mass difference and
electromagnetic effects. The effective chiral theory of low-energy QCD suggests relatively
large CSB in reactions involving neutral pions. The reaction

proceeds through CSB,
and the measurement of its cross section near threshold will be performed during the recently
extended lifetime of the IUCF Cooler. The measurement could provide a verification of the
effective theory prediction, and a determination of the light quark mass difference. The
workshop will begin with experimental presentations. The potential importance of the
measurement, and the challenging nature of the necessary calculation, requires a very
carefully executed computation of the cross section which involves different kinds of
expertise. The goal of this workshop is the creation of the necessary collaborations by
identifying the important experimental observables and bringing together theorists interested
in participating.
